John,

I used unsquashfs for stage2, edited usr/lib/anaconda/dispatch.py
changing the following lines.
    ("methodcomplete", doMethodComplete, ),
    ("dopostaction", doPostAction, ),
     changed to;
    ("dopostaction", doPostAction, ),
    ("methodcomplete", doMethodComplete, ),
ran ksquashfs on the unsquashed stage2 and it worked fine! :)

full description below... I was using BlueOnyx-5.2-20090107.iso
==================================================================
# Do the following to fix the issue not running %post scripts:
# Note that the *.img files use the squashfs file system.
# if the tools are not on the system yum install them. 
  yum -y install squashfs-tools mkisofs cdrecord
# insert install-cd into cdrom
  mkdir /mnt/cdrom
  mount /dev/cdrom /mnt/cdrom
  mkdir /home/BlueOnyx
  mkdir /home/BlueOnyx/ISOs
  mkdir /home/BlueOnyx/BlueOnyx-5.2-20090107
  cd /mnt/cdrom
# move the iso to a rw area
  tar -c * | tar -C /home/BlueOnyx/BlueOnyx-5.2-20090107 -xf-
  cd  /home/BlueOnyx/BlueOnyx-5.2-20090107
  cp /mnt/cdrom/.discinfo .
  umount /mnt/cdrom
# remove the install cd and insert a fresh CD
  cd /home/BlueOnyx/BlueOnyx-5.2-20090107/images  
  unsquashfs stage2.img
  cd squashfs-root
  vi usr/lib/anaconda/dispatch.py

    ("methodcomplete", doMethodComplete, ),
    ("dopostaction", doPostAction, ),
#and change to
    ("dopostaction", doPostAction, ),
    ("methodcomplete", doMethodComplete, ),
# note with vi you will have to use :w! to write the ro file
# recreate the ram file system:
  cd ..
  mksquashfs squashfs-root ../../stage2.img
  cp  ../../stage2.img stage2.img
  rm -rf squashfs-root
